66389061 ÷ 907 
Let's see how many times 907 fits into 66389061.

Step 1:
If we divide 6 by 907, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 907

Moving on to step 2:
If we divide 66 by 907, we get 0 and a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Fetch the next digit (3) from the dividend, attach it to 66 and continue: 663 / 907

Advancing to step 3:
If we divide 663 by 907, we get 0 and a remainder of 663.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 663 after subtracting 0 from 663.
Include the next digit (8) from the dividend after 663, then repeat: 6638 / 907

Moving on to step 4:
The number 907 fits into 6638 7 times, leaving a remainder of 289.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 6349 from 6638 to get 289.
Bring next digit (9) of the dividend behind the 289 and repeat the process: 2899 / 907

Going ahead to step 5:
907 can be fit into 2899 3 times, resulting in a remainder of 178.
Record the quotient 3 as the next digit in the result. 
Result so far: 73.0
The remainder is 178 after subtracting 2721 from 2899.
Append the next digit (0) from the dividend to 178 and continue with: 1780 / 907

On to step 6:
The number 907 fits into 1780 1 times, leaving a remainder of 873.
The number 1 becomes the next digit in our result. 
Result so far: 731.0
Deduct 907 from 1780 and we're left with 873.
Bring next digit (6) of the dividend behind the 873 and repeat the process: 8736 / 907

Advancing to step 7:
907 can be fit into 8736 9 times, resulting in a remainder of 573.
The number 9 becomes the next digit in our result. 
Result so far: 7319.0
Subtract 8163 from 8736 to get 573.
Fetch the next digit (1) from the dividend, attach it to 573 and continue: 5731 / 907

Moving on to step 8:
907 goes into 5731 6 times with a remainder of 289.
Put 6 as the next digit of the answer. 
Result so far: 73196.0
Subtract 5442 from 5731 to get 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Moving on to step 9:
907 can be fit into 2890 3 times, resulting in a remainder of 169.
The next digit of our result is 3. 
Result so far: 73196.3
The remainder is 169 after subtracting 2721 from 2890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Advancing to step 10:
907 goes into 1690 1 times with a remainder of 783.
The next digit of our result is 1. 
Result so far: 73196.31
Deduct 907 from 1690 and we're left with 783.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7830, and continue the process.

Let's proceed to step 11:
The number 907 fits into 7830 8 times, leaving a remainder of 574.
Record the quotient 8 as the next digit in the result. 
Result so far: 73196.318
If we take 7256 away from 7830, we end up with 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

Let's proceed to step 12:
5740 divided by 907 is 6 with a remainder of 298.
Record the quotient 6 as the next digit in the result. 
Result so far: 73196.3186
If we subtract 5442 from 5740, we get 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Going ahead to step 13:
907 can be fit into 2980 3 times, resulting in a remainder of 259.
The next digit of our result is 3. 
Result so far: 73196.31863
The remainder is 259 after subtracting 2721 from 2980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Moving on to step 14:
The number 907 fits into 2590 2 times, leaving a remainder of 776.
Put 2 as the next digit of the answer. 
Result so far: 73196.318632
If we take 1814 away from 2590, we end up with 776.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7760, and continue the process.

Advancing to step 15:
If we divide 7760 by 907, we get 8 and a remainder of 504.
Put 8 as the next digit of the answer. 
Result so far: 73196.3186328
If we take 7256 away from 7760, we end up with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Advancing to step 16:
907 can be fit into 5040 5 times, resulting in a remainder of 505.
Write down 5 as next digit of the result. 
Result so far: 73196.31863285
If we take 4535 away from 5040, we end up with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

The quotient of the division is 73196.31863285, and the remainder is 5.05e-07.
